Lol,....

I like the Robinair system. High in price though. $90...eek !

With my Coolflex hose's, I can't use any tool that squeeze's the radiator hose, because of vacuum.

A company has a nice looking thermostat housing with a bleeder valve that has a o-ring and can rotate 360°. But, it's like $90 !

I made my aluminum sand casted thermostat housing years ago, so I could drill & tap a hole and use it as a bleed valve.

Maybe use some type of nice looking bolt ?
Any ideas ?

Actually just looked on ebay and found a Trans Dapt with a bleeder, for $32.99 shipped.

Stupid question. Doesn't the intake need to be machined so the O-Ring has a groove to sit in, thus to seal ?
